OP1-OP6 are little storage areas for items that are bigger than what the
registers can handle, for example they point to variables, store
floating numbers, etc. each of the OPs are 11 bytes long. you have to
use calls to use the OPs. most of the routines are weird and seem
difficult, but thats the only way you can do some stuff on the calc
